Yea, you won't get 5GHz out of the C43, but it should do fine as long as you keep your overclock modest.

A whole bunch more from hardforum are about to be added. But one particular one of note I would think is this one. The failure took out both the motherboard and the CPU. and the CPU. Looks like CPUs being killed due to fried VRMs is not impossible.
post #513 of 1100
Are there any cases or reasonably clocked/volted X4's killing GD70/other MSI 4+1 boards?

i am thinking of getting a GD70+955, to see if i can kill it with dice.

I actually only have one posted with an 890FXA... (ask johnny.dot.exe for more details), but I do know it was somewhat of a trend with the old 790FX board and the x4 if you passed 1.5V for 24/7 OC

Meanwhile I just registered at hardforum, I'll be addressing them by linking them to the article here and perhaps providing assistance when necessary. It seems a lot of failures happen/are reported over there...

EDIT: Check this one out. A Jetway board blew in what was described as "failed choke". That's right, a smoking choke, not a MOSFET. This is definitely something new... I never even thought chokes could overheat and fail

I also just found out something about ASUS boards based on a recent post here on OCN and ones back on hardforum. They feature much better protection techniques. Once MOSFET temperatures are past a certain point (not CPU temps), the CPU throttles and/or the board shuts off. Looks like that's why I have never seen any ASUS VRM failure so far. However, that's still not to say that all ASUS VRMs are capable of pushing 125W.

Analyzing the list, i would say that it is more of a problem with 4+1 boards, and Thuban processors.

Just from looking over it, all of them are X6's except for 1.

Then, there are the 3+1 boards, which seem to like to fail with whatever they feel like.

ok, I pm'd johnny, and he had some interesting infomation:

Basically, all I did was increase the cpu voltage to 1.45v and the multiplier to 20.0x. As you can see, this is a rather conservative overclock for the type of gear I'm running, and shouldn't be anything that would fry a board under normal circumstances. Any OC extras, power savers safestepping, emp protection, etc were all disabled before overclocking per the norm.

When I would get around to running a CPU stress test, such as Prime95, some time in to the test my rig would just shut down. Upon trying to turn it back on, the lights/fans would just flicker. I unplugged the 12v CPU rail from the board, and the system would power(lights/fans/etc), just wouldn't boot obviously. RMA'd the board through newegg and they confirmed whatever the power went through before it hit the CPU...the VRMs/MOSFETs/whatever they're called...were fried. Same exact thing happened on the replacement board, under the same settings and everything. Newegg refunded my money outside of m 30day policy with them, which I used to get the crosshair. New board has been running great on the same exact overclock for almost 6 months now.
(this is with a phenom X4 965 BE, 890FXA-GD70, TX850 PSU)

very strange, that voltage is pretty low.

Umm durr. We went over this before. When my Gigabyte 3+1 blew out, it took my CPU, RAM, and PSU out with it. I'm LUCKY that's all that died with it.

Actually VRM failures taking out other parts is usually uncommon (statistically at least)
post #520 of 1100
xd, are you a time traveler?

If you are, we should warn dixson01974 that his VRMs are going to fail on September 1st 2011.
